foodcost.xls Version 1.0 September 2009 Food Waste Management Cost Calculator The Food Waste Management Calculator estimates the cost competitiveness of alternatives to food waste disposal, including source reduction, donation, composting, and recycling of yellow grease. Specifically, the calculator (1) develops an alternative food waste management scenario based on: your waste profile, availability of diversion methods, and preferences; and (2) compares cost estimates for a disposal versus an alternative scenario. The Cost Calculator demonstrates that environmentally and socially responsible food waste management is cost-effective for many facilities and waste streams. The more you know about your current waste management costs, the more accurate the calculator's estimate will be, but default values are provided for many variables. To use this Cost Calculator, navigate to the Inputs tab. There you will specify your type of organization (Grocery Store, Hospital, K-12 School, Restaurant, University, Prison, or Other Institutional Cafeteria); types and quantities of food waste; and availability of food recovery method(s). The Inputs tab has notes and instructions to guide you. Based on your inputs and associated costs, the Cost Calculator tab displays the 1-, 3-, 6-, and 10-year costs associated with food waste disposal versus an alternative scenario developed for your facility. The Cost Data tab provides default data including composting cost data and transportation costs. Users are encouraged to provide their own data for these costs if available. Cost data collected from sources dated before 2008 are adjusted for inflation. The Cost Graphs tab graphically portrays the changes in cost over time between the baseline and alternative scenarios developed for your facility based on your inputs and Cost Calculator results. The Benefits tab provides a summary of the environmental and other benefits associated with food waste diversion. The Composting Environmental Benefits tab estimates changes in variety of environmental measures based on the alternative scenario developed for your facility. This tab only measures changes resulting from composting preferences selected on the Inputs tab. The tab also provides a link to EPA's WAste Reduction Model (WARM), which estimates greenhouse gas (GHG) emissions of baseline and alternative waste management practices. You may enter the results of the Cost Calculator into WARM to estimate the change in GHGs from the baseline to the alternative scenario from composting. The Summary tab provides brief review of the alternative food waste scenario based on your inputs and preferences, and summarizes the scenario's financial and environmental results compared to the baseline. The Resources tab provides a summary of EPA's food waste hierarchy, as well as descriptive information and links to additional resources, including resources on the local availability of alternative food waste management methods. The Default Cost Data tab is a static version of the Cost Data tab. Refer to it if you change default data in the Cost Data tab, and subsequently want to re-enter default values. The Lookup tab contains calculator programming. The Waste Logbook tab provides an example of a food waste tracking spreadsheet that you can use to better characterize the quantity and nature of your food waste. Tracking food waste over time can help identify areas in which your operations can reduce food waste and achieve cost savings. Final Note: Macros need to be enabled for the calculator to work properly. Each time you run the calculator, you should save the file under a different file name to maintain a complete record.

Many institutions have succeeded at source reduction by decreasing portion sizes, eliminating food service trays i cafeterias, and using a la carte menus. To achieve source reduction, many facilities will require some form of food waste tracking. Paper tracking is simple and inexpensive, but may be time consuming and less accurate than automated tracking. Automated tracking can more expensive, but is likely more effective at targeting wasteful practices. A typical automated system costs $600 per month, and may typically result in source reduction of 3% or more. The costs of food tracking have not been incorporated into this calculator; however, facilities looking to achieve cost savings from source reduction should consider these costs.

Source reduction decreases the acreage of land necessary for food production and the environmental impacts associated with farming (e.g., fertilizer and pesticide use, water pollution, and some forms of air pollution) as well as the impacts associated with food transportation. Fights Climate Change The anaerobic decomposition of food waste in landfills releases methane, a greenhouse gas (GHG) 21 times more potent than carbon dioxide. Landfills account for 23% of US methane emissions and are the second largest anthropogenic source of methane in the country* Diverting food from landfills and incinerators lowers GHG emissions. Industrial Use programs that convert food oil to fuel reduce fossil fuel energy consumption and also decrease GHG emissions. Protects soil through composting Compost enriches poor soils, serves as an erosion deterrent, increases the water retention capacity of the soil, and can be used as a substitute to fossil fuel based fertilizers in some applications. Strengthens organizations and communities Americans throw away more than 25% of the food we prepare. Establishing a food waste diversion program helps to feed the hungry and alleviate food shortages at food pantries and soup kitchens. Diverting food to pantries and food rescue organizations is recognized as the right thing to do by employees and community members. Organizations can develop good will and positive outreach programs around food waste diversion programs. *U.S. Emissions Inventory 2009: Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2007 ------- EPA Food Waste Calculator 2009.xls Environmental Benefits of Composting TABLE 1: Quantity of Annual Food Waste Composted in the Alternative Scenario Food Waste Category Pounds Tons Pre-Consumer Prepared / Whole Foods Pre-Consumer Trim Waste Post-Consumer Plate Waste Total Pounds To view a summary of the alternative scenario, including potential cost savings and environmental benefits, see the Summary tab, or click this cell. To evaluate greenhouse gas (GHG) emissions reductions resulting from composting your food waste according to the alternative scenario, EPA recommends that you use the WAste Reduction Model (WARM). EPA created WARM to help solid waste planners and organizations track and voluntarily report greenhouse gas emissions reductions from several different waste management practices. The latest version of WARM is available both as a Web-based calculator and as a Microsoft Excel spreadsheet and can be accessed at: http://www.epa.aov/climatechanae/wvcd/waste/calculatorsAA/arm home.html Similar to the Food Waste Management Cost Calculator, WARM requires you to enter baseline and alternative management scenarios. To estimate potential GHG reductions from composting activities based on the alternative food waste scenario, enter total quantity composted in tons from Table 1 (above) into WARM'S Baseline (Step 1) "Tons Landfilled" column for food scraps. Then, enter the same quantity into the Alternative Management Scenario (Step 2) into the "Tons Composted" column for food scraps. To view results, set the remainder of WARM'S assumptions for landfilling characteristics and transport distance. WARM provides you with tips to set these settings. Using compost can reduce or eliminate the need to apply fertilizers and pesticides on lawns, gardens, and other landscaping. Table 2 shows potential reductions in environmental impacts resulting from composting under the alternative scenario. The emissions reduction factors, developed using life-cycle assessment (LCA) methods, assume that composting will result in a 50% reduction and fertilizer use. The environmental impact categories are presented in terms of the equivalent pounds of a common pollutant (e.g., carcinogens are measured in pounds of benzene equivalent).

Based on your inputs, you would source reduce 0 pounds of non-perishables, 0 pounds of pre-consumer prepared/whole foods, 0 pounds of pre-consumer trim waste, and 0 pounds of post-consumer plate waste for a total of 0 pounds annually. If you employ the management methods listed above, your facility would save roughly 0 after 1 year and 0 after 10 years. Annually, based the quantity of food waste composted, your facility could potentially reduce the following: -Particulates equivalent to reducing 0 pounds of PM2.5, which has been linked to respiratory and heart disease. Reducing this level of PM2.5 emissions is equivalent to removing 0 cars off the road for one year. -Toxics equivalent to 0 pounds of toluene, a toxic chemical that has been found to have acute, long-term, and developmental effects on human heath. -Carcinogens equivalent to 0 pounds of a benzene, a toxic chemical proven to cause leukemia in humans. -Eutrophication equivalent to 0 pounds of nitrogen, commonly used as a nutrient in fertilizers. -Acidification equivalent to 0 pounds of sulfur dioxide (S02) per year. S02 has been linked to acid rain, which damages trees, crops, historic buildings, and monuments; and makes soils, lakes, and streams acidic. This level of S02 emissions is equal to the amount of S02 generated during the production of 0 Kilowatt-Hours of electricity at the most polluting power plant (in terms of S02) in the US. -Ecosystems toxicity equivalent to 0 pounds of 2,4-D, a commonly used agricultural and residential pesticide. ------- EPA Food Waste Calculator 2009a.xls Back to Inputs Tab Food Waste References, Definitions, and Additional Resources Food leftovers are the single-largest component of the waste stream by weight in the United States. Food waste includes uneaten food and food preparation scraps from residences or households, commercial establishments such restaurants, and institutional sources such as school cafeterias. Americans throw away more than 25 percent of the food we prepare, about 96 billion pounds of food waste each year. In total, the nation spends about 1 billion dollars a year to dispose of food waste. Food Waste Recovery Hierarchy EPA has developed a food waste recovery hierarchy to illustrate how productive use can be made of excess food. The hierarchy emphasizes practices that provide the greatest ecological, economic, and social benefits, with disposal as the last option. Source Reduction - Reduce the volume of food waste generated by aligning food supply more closely with food demand. Feed Hungry People - Donate extra food to food banks, soup kitchens and shelters. For more information, refer to EPA's guide titled "Feeding the Hungry and Reducing Solid Waste through Food Recovery" at http://www.epa.aov/epawaste/conserve/materials/organics/pubs/wast not.pdf Feed Animals - Provide food to farmers to use as animal feed. Industrial Uses - Provide fats, oils, and greases (FOGs) for biodiesel production or certain types of food scraps for rendering. Composting - Convert food scraps into a nutrient rich soil amendment through aerobic decomposition. For more information, refer to EPA's "Guide to Commercial Food Composting" at: http://www.epa.aov/epawaste/conserve/materials/oraanics/food/fd-guide.htm Source Reduction Feed Hungry People Feed Animals Industrial II Co niu (j sling Source Reduction and Food Waste Tracking Source reduction is the practice of reducing the overall volume of food waste generated. Typically, facilities identify and eliminate excess food waste through changes in food purchasing, storage, handling, and use. Source reduction leads directly to cost savings, resulting from avoided purchases and subsequent waste hauling fees. By separating food waste, businesses can inventory their excess food supply and implement appropriately targeted source reduction strategies. Facilities may track food waste through paper tracking or more sophisticated automated tracking systems. Paper tracking is typically not expensive, but may be time consuming. See the Waste Logbook tab for paper tracking template. Automated systems can reduce tracking time and help target specific areas (e.g., purchasing, spoilage, trim waste) for source reduction. For one example of an automated food waste tracking system, see: http://www.leanpath.com/lpweb/index2.htm For additional food waste tracking tips and tricks, see: http://blog.leanpath.com/7page id=618 Note: Identifying these websites does not constitute an endorsement by EPA of their products or services. Food Waste Diversion Methods Food Rescue Food Rescue programs focus on the recovery of prepared meals and other perishable foods. For general information about this class of food recovery program and for details about the food preparation and delivery requirements, see: http://feedingamerica.org/partners/product-partners/perishable-food.aspx Food Banks Traditional food bank programs focus on recovering and collecting non-perishable food items, generally distressed, surplus, or unsaleable products from grocery stores and supermarkets. Some food banks will also recover fresh produce. For general information about this class of programs, see: http://feedingamerica.org/partners/product-partners/distressed-unsaleable-product.aspx Food Diversion to Animal Feed There are few formal programs to facilitate the diversion of food waste to animal feed, though conditions and available resources can vary throughout the country. To locate an interested livestock farmer, potential donors should begin by contacting a local university agricultural extension office or their county agricultural commissioner's office. General information for those interested in this management method is provided by the California Integrated Waste Management Board: http://www.ciwmb.ca.gov/FoodWaste/AnimalFeed/ Page 1 of 9 ------- EPA Food Waste Calculator 2009a.xls Industrial Uses - Yellow Grease Recovery of yellow grease to make biodiesel is an increasingly available option. Restaurants, kitchens, and other commercial food establishments may be able to locate a biodiesel company willing to pick-up their used yellow grease and convert those materials into biodiesel fuel. These companies will often provide the pick-up service free of charge. To identify a company, do an Internet search for the name of your city and "biodiesel collection." As an example of yellow grease collection service, information about two biodiesel companies in New York and Southern California is available at the following links: http://nvc.tristatebiodiesel.com/collect.htm http://www.newleafbiofuel.com/oilCollection/commitment.html Note: Identifying these websites does not constitute an endorsement by EPA of their products or services. On-Site Outdoor Composting On-site composting can be done using two mechanisms: the traditional compost pile, discussed here, or through an in-vessel composter, discussed below. Given the availability of appropriate space and volume of appropriate wastes, certain facilities may already have a functional on-site compost pile or they may be interested in starting such a pile. Introductory information about the compost pile method, including necessary ingredients and applicable wastes, can be found at: http://www.epa.aov/epaoswer/non-hw/composting/bv compost.htm On-Site In-Vessel Composting In-vessel composting is a process of composting in enclosed reactors such as metal tanks, through which air flow and temperature are controlled. There are many in-vessel composters that can be used on-site in commercial and institutional applications. Learn more at: http://www.epa.aov/epaoswer/non-hw/composting/vessel.htm If your facility generates over 500 pounds of food waste per day and you need site-specific cost data for in-vessel composting, you may want to contac the manufacturers below or contact a provider that services your area: Green Mountain Technologies http://www.gmt-organic.com/ NaturTech Composting http://www.composter.com/composting/naturtech/ BWOrganics, Inc. http://www.bworganics.com/ Note: Identifying these websites does not constitute an endorsement by EPA of their products or services. Off-Site Composting Taking organics to a composting facility depends on the accessibility of local composting sites that will accept food and other organics. To find out about composting sites in your area, contact your state or local department of environmental protection, public works, or equivalent that has responsibility for solid waste.
